Shouldn't this be CONFIG_PINCTRL_TEGRA_XUSB=m? However, the error will occur either if you compile as a module or not, but the changelog should be accurate nonetheless. > The problem is below line in drivers/pinctrl/Makefile > obj-$(CONFIG_PINCTRL_TEGRA) += tegra/ > > So even CONFIG_PINCTRL_TEGRA_XUSB=y is set, kbuild still does not compile > the code in drivers/pinctrl/tegra folder if !CONFIG_PINCTRL_TEGRA. I was able to reproduce this by having CONFIG_PINCTRL_TEGRA_XUSB=y and !CONFIG_PINCTRL_TEGRA. So maybe that's all you need to say in the changelog with regard to the kernel config and get rid of the initial statement about kernel config. > phy-tegra-xusb.c does not use any symbol from pinctrl-tegra.c, > so build pinctrl-tegra.c only when CONFIG_PINCTRL_TEGRA is set. > > Signed-off-by: Axel Lin <axel.lin@xxxxxxxxxx> > --- > drivers/pinctrl/Makefile | 2 +- > drivers/pinctrl/tegra/Makefile | 2 +- > 2 files changed, 2 insertions(+), 2 deletions(-) > > diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile > index 2ed0b3f..25ec450 100644 > --- a/drivers/pinctrl/Makefile > +++ b/drivers/pinctrl/Makefile > @@ -25,7 +25,7 @@ obj-$(CONFIG_PINCTRL_PISTACHIO) += pinctrl-pistachio.o > obj-$(CONFIG_PINCTRL_ROCKCHIP) += pinctrl-rockchip.o > obj-$(CONFIG_PINCTRL_SINGLE) += pinctrl-single.o > obj-$(CONFIG_PINCTRL_SIRF) += sirf/ > -obj-$(CONFIG_PINCTRL_TEGRA) += tegra/ > +obj-$(CONFIG_ARCH_TEGRA) += tegra/ > obj-$(CONFIG_PINCTRL_TZ1090) += pinctrl-tz1090.o > obj-$(CONFIG_PINCTRL_TZ1090_PDC) += pinctrl-tz1090-pdc.o > obj-$(CONFIG_PINCTRL_U300) += pinctrl-u300.o > diff --git a/drivers/pinctrl/tegra/Makefile b/drivers/pinctrl/tegra/Makefile > index a927379..d9ea2be 100644 > --- a/drivers/pinctrl/tegra/Makefile > +++ b/drivers/pinctrl/tegra/Makefile > @@ -1,4 +1,4 @@ > -obj-y += pinctrl-tegra.o > +obj-$(CONFIG_PINCTRL_TEGRA) += pinctrl-tegra.o > obj-$(CONFIG_PINCTRL_TEGRA20) += pinctrl-tegra20.o > obj-$(CONFIG_PINCTRL_TEGRA30) += pinctrl-tegra30.o > obj-$(CONFIG_PINCTRL_TEGRA114) += pinctrl-tegra114.o This works for me.
